摘要
Depositing additional Cu layer on top of a Co thin film changes the magnetic properties of buried layer significantly. Employing in situ magneto-optical Kerr effect (MOKE) to assess the magnetization behavior of uncovered and covered Co layer grown on Cu (0 0 1), the hysteresis loops give averaged, macroscopic response of the layered system. The microscopic information was examined through elementspecific domain images acquired by the X-ray photoemission electron microscope (PEEM). Based on the image analysis, evidence of magnetization switching in some regions of the as-deposited Co layer upon capping 1 ML of Cu was found. (C) 2006 Elsevier B.V. All rights reserved.
